  • Publication number: 20120268046
    Abstract: A control device for an alternating current motor according to embodiments includes a current distributor and a phase estimator. The current distributor divides a torque command by using a control phase and outputs a component that contributes to a mechanical output of the motor as a ?-axis current command and a component that does not contribute to the mechanical output as a ?-axis current command. The phase estimator computes a phase at which a ?-axis component of an addition amount of the output of the current controller and a voltage drop amount of inductance of the motor becomes zero and outputs the computed phase as the control phase.

  • Patent number: 8258604
    Abstract: To provide a technique that can improve the data retention characteristic of an MRAM device by improving the resistance against an external magnetic field in a semiconductor device including the MRAM device. A first magnetic shield material is disposed over a die pad via a first die attach film. Then, a semiconductor chip is mounted over the first magnetic shield material via a second die attach film. Furthermore, a second magnetic shield material is disposed over the semiconductor chip via a third die attach film. That is, the semiconductor chip is disposed so as to be sandwiched by the first magnetic shield material and the second magnetic shield material. At this time, while the planar area of the second magnetic shield material is smaller than that of the first magnetic shield material, the thickness of the second magnetic shield material is thicker than that of the first magnetic shield material.

  • Publication number: 20120061850
    Abstract: To achieve a reduction in cost of a semiconductor device, in a common board (a wiring board), a plurality of bonding leads each extend toward the center of the board, and a solder resist film as a die bonding region supporting a minimum chip is coated with a die bonding material. With this, even when a first semiconductor chip as a large chip is mounted, wire bonding can be performed without causing the die bonding material to cover the bonding leads. Thus, development cost can be reduced to reduce the cost of the semiconductor device (LGA).

An electric vehicle data processing system is employed that performs, on an electric vehicle battery module having a plurality of battery cells installed therein, authentication of individual battery cells and the battery module itself in a hierarchical manner using a microcomputer. An electric vehicle is configured so as to cause the microcomputer of the data processing system to accumulate voltage history and charge history of the batteries in a nonvolatile storage circuit. The history information and the electric vehicle ID can be gathered by a maintenance device and a data server via an electronic control unit of the electric vehicle. A maintenance service system may thus be provided.

  • Publication number: 20100233334
    Abstract: A process for producing a food enclosed in sealed containers which is free from a trouble during production that water spills from the containers or a perforating jig falls into the containers and in which a heat treatment can be conducted without causing quality unevenness. A food (1) is placed in containers (2). The containers (2) filled with the food (1) are sealed with a primary film (4) having a through-hole (3) to obtain a sealed-container-packed food (A). This sealed-container-packed food (A) is disposed in a heating vessel (7) having a steam inlet part (5) and a steam discharge part (6). Steam is introduced through the steam inlet part (5) into the heating vessel (7) to heat the sealed-container-packed food (A) while discharging the steam through the steam discharge part (6). Thereafter, a secondary film (8) is bonded to each container through the primary film (4) so as to cover the through-hole (3).

  • Patent number: 7645614
    Abstract: The present invention provides a method of analyzing the specific interaction between a molecule to be analyzed and a molecule that specifically interacts with the former molecule on a solid phase using a molecule-immobilized solid phase support mixture prepared by binding the subject molecule to the solid phase support without specifying the binding position on the molecule side, particularly a method wherein the immobilization is conducted via a spacer introduced to the molecule without specifying the binding position on the molecule side, which method makes it possible to identify and select only a molecule that exhibits a specific interaction with a molecule to be analyzed, without an investigation of structure-activity correlation, which has conventionally been essential, and hence enables an analysis of the interaction between these molecules.
